The "Men in Black" sequel is a frenetic sci-fi comedy with Will Smith and Tommy Lee Jones back as Jay and Kay  agents of a government organization that keeps the masses oblivious to a global infestation of extraterrestrials and protects Earth from alien criminals. In "II," a despot from another planet takes the form of a lingerie model (Lara Flynn Boyle), scours Manhattan to find an ultimate weapon and tries to get revenge on Kay for a previous subjugation. As in "MIB," the spoofery springs from the idea that the populace is unaware of the exotic, terrifying creatures hiding in plain sight. No matter how outrageous the beast and extensive the havoc it wreaks in public, Jay and Kay use a device called a neuralizer to make bystanders forget what they saw. "MIB," action-packed and tongue-in-cheek, was a hard act to follow. For all the sequel's capricious energy, it lacks the original's sense of surprise. Maybe "II" would be more impressive if the studio used the neuralizer on anyone who saw the first film.
